diamond coated popcorn endmills milling cutter for high quality CFRP1

Side milling tests of CFRP (Carbon Fiber Reinforced Plastics) without coolant are carried out by DLC (Diamond-Like Carbon)-coated carbide end mills. Four types of DLC-coated end mills are chosen: UBMS (UnBalanced Magnetron Sputtered) and AIP (Arc Ion Plated) coatings having different helix angles, respectively. The surface integrity is evaluated in terms of 3D profiles of the machined surface, generation of fluffing, delamination and pull-out of the carbon fiber. The cutting force and tool wear with respect to the fiber orientation are also examined. The inclination milling with high helix angle end mill is proposed in which the end mill is tilted in such a way that the resultant cutting force acts parallel to the work surface. This unique approach enables to reduce tool wear and to improve surface integrity of machined surface of CFRP.

The diamond-coated popcorn end mills for CFRP is a cutting-edge tool, which is specially designed for the precise and efficient processing of carbon fiber reinforced polymer (CFRP) materials. This innovative milling cutter combines the strength and durability of Diamond Coated Drill Bit with the unique design of corn teeth end mills, resulting in exceptional performance and longevity. The diamond coating enhances the cutting edge's hardness and wear resistance, ensuring extended tool life and improved machining accuracy. With its ability to effectively mill CFRP materials, this diamond coated popcorn end milling cutter is revolutionizing the aerospace, automotive, and other industries where CFRP components are widely used.
